Visible result from first use! Best blue shampoo I've purchased to date, and good conditioning effect. I would recommend.

I use this rather than purple shampoo on dark/ medium blonde hair. It really helps to brighten it and take out the brassy tones. It’s not drying.

Not sure why the mediocre reviews- clearly expecting more than they’ve pay for.The shampoo works very very well for a SHAMPOO. It is not bleach or a colour stripper- however it is the most effective and gentle route to correct colour I’ve found. My hair has been coloured black for years, after bleaching and going red I was left with so many brassy tones as it grew out.For best results I’ve found brushing your hair before showering, wetting hair as your brush and then brushing the shampoo in, leaving for as long as you can and then washing out works best. The after photo is three washes over a week which I’m over joyed about as nothing else I’ve done has touched the brassy colour. Couldn’t recommend more. FYI it is very pigmented to ensure to wash hands and use a dark towel :)

Fast delivery. Seems effective and only used once. Left on for about 5 minutes. Hair didn't feel dry after shampooing and didn't make too much mess although I wore gloves just in case. Expecting to see further results per use. Not used Blue shampoo before so nothing to compare with but over all can't complain.

Not blue but purple. Not what I was looking for

Never used a blue product before but after deciding to lightening my hair at home and going a tad brassy have used this with the matching conditioner and it worked a treat for me toning the brassiness.

I’ve got brown hair but had previously dyed it a slightly darker shade of brown and over the years it had gone ginger. I have been using for three months (without the conditioner) and it has made a slight difference. I would recommend using this as the last product last otherwise my usual conditioner makes this have zero impact. There has been some change but not much and I think for the cost I expected more. I wouldnt buy it again

Review from the wife: Heavens they weren't wrong when the said blue. Recently changed hair colour and the new shade accentuated the brassy tones in my hair. Worked first time. Now have dark auburn lights as opposed to a certain boy wizard's best friend !!!
